In reservoir management, seismic surveillance is crucial to maximize the value of the field. It is not only useful in revealing the current reservoir situation, but also in managing future risks. In a typical seismic monitoring project, repeated data acquisition and processing are required for...

Monte Carlo methods are a simple, effective, and widely deployed way of approximating integrals that prove too challenging for deterministic approaches. This thesis presents a number of contributions to the field of adaptive Monte Carlo methods. That is, approaches that automatically adjust the...

Grasslands cover 30% of the planet’s terrestrial surface and provide habitat and forage for livestock and wildlife. In addition, grasslands have the potential to mitigate climate change by sequestering substantial amounts of carbon (C) in the soil. However, the ability of grassland soils to...

We introduce "optimization through protocol selection" (OPS) as a technique to improve bulk-data transfer on shared wide-area networks (WANs). Instead of tuning the parameters of a network protocol, our empirical results show that the selection of the protocol itself can result in up to four...

Adaptive phase synchronization techniques for unbalanced and distorted three-phase voltage system
DownloadFall 2010
Interfacing and operating AC power electronic systems requires rapid and accurate estimation of the phase angle of the power source, and specifically of the positive sequence of the three-phase utility grid voltage. This is needed to ensure reliable operation of the power control devices and of...
